François & Jean dans la communication

How communication differs from the 60's to the 21st century?I'm writing a research report for my English Class and we are required to write a paper by interviewing a person (at least 50 years old) about different aspects of his/her culture when they were a teen.
I'm writing mine on the difference of life with advances of communication, such as cell phones, computers, email, fax machines, etc.
We must ask our interviewee 15 questions about our topic.
